Preparing for Installation

Setting the Elevation and Attaching the Fine Tuning Adjustment

Use the elevation setting coordinate you wrote down on page 8 to preset the elevation of the dish, and then attach the fine tuning adjustment tool.

1.Use a 1/4” x 1/2” carriage bolt, a washer, and a flange nut to attach the L-bracket to the elevation slot.

2.Rotate the support sleeve so that the elevation indicator (white line), NOT the bolt or the L-bracket, lines up with the tick mark on the mast corresponding to the elevation setting you recorded earlier.

3.Tighten the flange nut securely and then secure a second 1/4” x 1/2” carriage bolt, washer and flange nut on the opposite side.

Tip

To get the correct elevation, line up the painted edge inside the curved groove of the clamp with the degree marker. Do NOT use the bolt.

4.Thread the bolt from the second L-bracket through the first L-bracket until the bracket lines up with the hole on the mounting assembly. Double-check your elevation setting and adjust if necessary.

5.Use a 1/4” x 1/2” carriage bolt, a flat washer, and a flange nut to attach the L-bracket to the mast clamp.,
